Indicator I9 is slidably mounted for 55 movement relative to chart i8 through the agency of hub 24 and shaft 25 and is connected with presser plates 4 and 'l through the medium of pivot link 26, bell crank 2l and standards 28 and 29. Standard 28 is welded or otherwise rigidly secured at one of its ends, as at 30, to bar H which controls the movement 0f presser plate 4 and at its opposite end, as at 3|, is pivotally connected to bell crank 2l at its rocker point. Standard 29 is welded or otherwise rigidly secured, asiat,f32,'to'holder I3 and at its opposite end, as at 113, is pivotally secured to one end of bell crank 2l. Link 26 pivotally connects the opposite end of bell crank 2l, as at 34, to indicator i9 as at 35.

In operation, the' presser plates 4 and 'I are moved to their innermost presserv movements against bacon slab I0 in the manner hereinbefore described, whence it is seen, indicator I9 is'moved relative to chart i3, first, by direct movement, by presser plate Il through the medium ofarm 31 of bell crank 27 and link 26, and secondly, by indirect movement, by presser plate 1 through the medium of bell crank 21 and link 2G. i 1

It Will be seen. that the present, invention, although exemplified for use for determining the number of slices a bacon slab will deliver per unit Weight, may be used for determining the crosssectional areas of other parallelepiped articles for different purposes.
